To all whom it may concern.'

Be it known that I, Eme F. G. H. FAURE, citizen of they French R ublic, residing at Erie', in the county of erieand State of Pennsylvania., have invented certain new and useful Improvements in Self-Oiling Bearings, of which the following is a full, clear, and exact specification.

My invention relates to self oiling bear ings, and although the use thereof is well adapted for dynamo electric-machines, it is of advantage in bearings generally.-

Among the objects of my linvention may be stated the provision of means for elliciently oiling the bearing, and securing a uniform supply of oil and reliability in operation.

A further object is to provide oilin means which may be simply constructed, an which will occupy only a comparatively small amount of space and so reduce the size of the journal box.

It has been customary to use bearings 1n which the bearing sleeve is slotted in the upper portion at one or more points, andnm each slot of which is located a ring which engages the upper portion of the shaft and which is of sufficient diameter to have itsy between the bearing surfaces. One objec-v tion to this construction is the necessity for making the ring of large diameter in order that it may extend wellbelow thefjshaft into a considerable quantity of oil. This ring having a considerably larger diameter than the shaft, requires a journalbox whichiis milch wider than would otherwise be neces-l sary. By my invention this large width of bearing is avoided. Also in the above mentioned type of ring oiling device, the oil supplied to the bearing is merely that which covers the surface of the ring, but by use of my invention the amount of oil supplied is greatly increased. Also in the construction formerly used, the ring is likely to stop in its movement and ceases to supply oil by reason of its light weight and poor ric-' tional contact with the upper portion of the shaft. By my invention this is overcome, and an efficient and reliable oiling device produced. These and other features of my invention will be understood yfrom the accompanying drawings, and description thereof. v

Figure l is a plan view of a bearing embodying my invention; Fig. 2 is a. longitudinal sectional view of the bearing taken in a vertical plane, and Fig. 3 is a sectional view on line 3-3, of Fig'. 2.

The bearing is shown as havingn pedestal l which supports the lower ortion of the Journal box, the per half 2 orming the re` movable cap. I'Vlthin the journal box is a bearing sleeve 3 having a spherical. bearing surface 4 which engagesl a similar surface in the Journal'box, thus forming a bearing of the self alining type. In the lower half of the journal box is formed an oil reservoir, the parts 5, 5 of which are connected by an opening 6 shown in Fig. 2. The upper portion of the bearing sleeve is shown slotted circumferentially at 7, 7 and in each of these slots and encircling the shaft and portion of the bearing sleeve is a chain 8 of 4suitable form. I have shown a bicycle chain in the drawings and have foun this rto produce good results in practice. The chain han as shown in Fig. 3, its lower portion extensing into the part 5 of the reservoir.' Uetween the chain and the shaft is locatedia small sized ringl9 having a recessed outer rim for receiving the chain and having a series of holes 10 at intervals throughout the circumference of the ring. The ring does not extend into the oil reservoir but serves as a carrier for the chain. y

In operation, the rotation of the shaftserves to move the chain through the medium of the ring The oil gathers`on the chain over the surface of the links and between the links and results in carrying a much larger quantity of oil to the bearing than in the case of merely using a ring.

When the coated portion of thechain passes within the slot 7, the oil will flow from the chain and ring onto the bearing surfaces. Any'tendency of the oiling means to stop in its rotation is overcome by reason of the weight of the chain on the lring which gives .good frctional contactbetween the vring and shaft.

It will be seen that the width of the oil ing means is very much less than when the old type of oil ring is used, and the width of thejournal box is correspondingly reduced. Also,the cost of manufacture is less by the use of my invention. by reason of its coin aetness and in avoiding the cost of making the large brassrings formerlir used. Another advantage of my invention is: that the rute of movement of the oli-.1in is substentinlly cor'istz'rnt:l The chain passing through theoil places a drag-upon the'device and so' 'prevents' .en unduly' high speed or sudden change in speed and thus overeornes splashing 'o the oil, The carrier for the chain' is importent in that t ecrit-away portion of the sleeve is Slight 'compared with ziconstruction Where :i chain' with no o:1.r-

rie-r is used; W'ith "the ehein ilone, the' sleeve must be out nivay'" so that the ehain chnin 'und sleeve the' 'movement of the chain to lbe irregolari or 'stopentireljf'a and i 2C also causes most of ,the o iflt'o'be wiped 'olf the chain before reaching. the shaft.
